The NFT tubes support structure is getting rebuild. The old wooden structure is being replaced with concrete blocks for the legs at both ends. Here you can see the one end being build. The other end will be bit harder, due to having electric line coming up thru it. I'm hoping to have the other end completed tomorrow. The new legs/walls are 39 inches wide, compare to the old structure of 24 inches. This should allow me room for four NFT tubes.
I thinking that I might try a doing a deep water NFT system with two tubes this year. Along with the standard NFT system.
